Die Wissenschaftsplattform Nachhaltigkeit 2030 ist ein zentraler Ort der Wissenschaft, an dem sie drängende Fragen der Nachhaltigkeits-politik reflektiert und diskutiert – im Austausch mit Politik, Wirtschaft und Gesellschaft. Wissen für Nachhaltigkeit wird dort zusammengetragen und weitergetragen, insbesondere im Hinblick auf die Umsetzung der Deutschen Nachhaltigkeits-strategie. Die Plattform arbeitet unabhängig und ist systematisch eingebunden in den offiziellen politischen Steuerungs-, Dialog- und Umsetzungsprozess der Agenda 2030. Träger der Plattform sind SDSN Germany, DKN Future Earth und das IASS Potsdam.

Objective: Perspectively, we intend to develop an artificial photoreceptor based on organic materials for retinal prosthetic devices. Currently, we aim to elucidate the stimulation mechanism on a cellular model system. Materials and Methods: We conduct electrophysiological patch clamp recordings [for full text, please go to the a.m. URL], Artificial Vision 2017

32nd European Photovoltaic Solar Energy Conference and Exhibition; 1310-1315, Presented here is a study of titanium dioxide thin films for their use as an electron transport layer (ETL) in perovskite solar cells (PSCs). These studies were performed on both the amorphous and polycrystalline (anatase) phases of titanium dioxide (TiO2). Amorphous films were deposited by reactive e-beam thermal evaporation of titanium in oxygen atmosphere. To obtain the anatase phase, these films were annealed in air at 500C for 30 minutes. The effect of the oxygen flow rate on the transmissivity of both the amorphous and anatase films was investigated. It is shown that, for amorphous films, the transmissivity increases with increasing the oxygen flow rate, while the transmissivity is almost constant for the anatase case. Also, the dependence of the resistivity on the oxygen flow rate for the amorphous films was investigated. Both the amorphous and anatase films were integrated into PSCs. It is shown that, for amorphous films, the Voc increases with increasing the oxygen flow rate, while it shows no clear trend for the anatase case. Finally, the effect of a molybdenum oxide (MoOx) layer between the spiro-MEOTAD and gold back-contact was investigated. This addition leads to an improvement in the cell performance, achieving an efficiency of 8.1%.

In the case of magnetocardiography (MCG), gradiometry is a commonly used method to reduce environmental noise. Here, the balance of the gradiometer is one of the main parameters determining the achievable noise reduction. In earlier work, we reported the use of frequency dependent gradiometer coefficients to effectively balance a gradiometer consisting of signal and reference sensors. In this work, the advantages of adaptive determination of these coefficients during a measurement without perturbing the MCG signal are investigated. MCG measurements were recorded with first and second order high temperature SQUID gradiometers inside and outside magnetic shielding. It will be shown that the heart signal is not distorted by applying our software noise reduction technique. Furthermore, by recalculation of gradiometer coefficients during the MCG measurement, an improved signal-to-noise ratio is achieved. The optimum repetition time for coefficient recalculation is determined.
